The point I am trying to make is about the unexpected behaviour of the
DIR command and that is if a directory exists with the same name as the
file one is searching for, the directory listing is terminated early
without error.
In my example, if the Q directory is renamed to Q4 and the command "DIR
Q /S /B " issued, all occurrences of Q file are found.
Eg.
f:\a12\Q.A
f:\a12\j\Q
f:\a12\q.a\Q
f:\a12\q.a\Q.A
f:\a12\q1\Q
f:\a12\q1\Q.A
f:\a12\q4\Q
f:\a12\q4\Q.A
f:\a12\q4\Q.ASM
f:\a12\ts\Q
f:\a12\ts\Q.A
f:\a12\ts\Q.ASM
With the Q directory in place and issuing the command "DIR Q /S /B ",
only files in the Q directory are displayed.
Eg.
f:\a12\q\Q
f:\a12\q\Q.A
f:\a12\q\Q.ASM
f:\a12\q\Q1
f:\a12\q\Q12
I suspect that if there are deeper levels of directories and Q files are
at levels prior to the Q directory, these Q files will be displayed
until the Q directory is encountered and the then listing will stop.
Further Q files will not be found/ displayed. I have not verified this.
Is this expected behaviour, an anomaly or a bug?

Regardless of whether they're files or directories, if there is no
file extension, then don't put on the second star, just a *. will do
the search for you. By placing the second star, you're making the os
search for extensions by default. Leave it out, and it will search
for just files w/o them. I only said before that typically directories
don't have extensions, so that's an easy way to find them. but in
your case, The same thing applies for files without extensions.

Hi
I am looking for files named Q and not directories named Q. In my
case I have thousands of assembler text files without filename
extensions. It comes from early days starting out with TSC Flex and
Uniflex followed by the Mark Williams Coherent operating systems.

Don't know if it helps, but I've found that if you want *just*
directory names, and you don't have a directory program that allows
you to set flags, so it only shows directories, then the best way to
get them is to do something like:
dir *.
Since most directory names don't have extensions, this only picks
out the directory names (and of course, any files without
extensions, but those are rare), so that should find the q directory
for you with little to no trouble.

Hi All
It appears that if a directory exists with the same name as the

I was searching for a files named "Q" with no extension. I used the
commands "DIR Q /S /B" and "DIR Q. /S /B", but it only revealed
files in a directory named "Q".
An example directory structure is shown below. Note that most of
the file names below do not have extensions. The file named "Q"
appears in all the subdirectories.
I was puzzled and decided to dig a little further. Is this correct
behaviour for the DIR command or a misunderstanding on my part
about file name matching? Perhaps an anomaly or a bug? I have tried
various DOS's with the same result, the DIR command being an
internal one. I have also tried XCOPY and XXCOPY with the "/L"
option and it also only finds the files in the "Q" directory. Any
thoughts as to what's going on?

Directory of f:\a12\*.*
[.] [..] [J] [Q] [Q.A]
[Q1] [TS]
Directory of f:\a12\j\*.*
[.] [..] Q
Directory of f:\a12\q\*.*
[.] [..] Q Q.A Q.ASM
Q1 Q12
Directory of f:\a12\q.a\*.*
[.] [..] Q Q.A
Directory of f:\a12\q1\*.*
[.] [..] Q Q.A Q99
Directory of f:\a12\ts\*.*
[.] [..] Q Q.A Q.ASM
Entering the command below gives the following result.
F:\>DIR Q /S /B
f:\a12\q\Q
f:\a12\q\Q.A
f:\a12\q\Q.ASM
f:\a12\q\Q1
f:\a12\q\Q12
The Q file is only found in the Q directory.
Same result as above with:-
F:\>DIR Q. /S /B
Typing command:
F:\>DIR Q.? /S /B
Gives this result.
f:\a12\Q
f:\a12\Q.A
f:\a12\j\Q
f:\a12\q\Q
f:\a12\q\Q.A
f:\a12\q.a\Q
f:\a12\q.a\Q.A
f:\a12\q1\Q
f:\a12\q1\Q.A
f:\a12\ts\Q
f:\a12\ts\Q.A
The Q file is now found in all the subdirectories.
